+This chapter lists the most common issues encountered when using \rotare. If
+you find an issue that is not documented here, please check the
+\href{\rotareIssuesURL}{issue tracker} and fill a new issue report if

+\section{<Library> cannot be found or cannot be imported}
+\label{sec:user:trouble:missingLib}
+
+\rotare depends on some libraries to conduct some simple tasks (mostly airfoil
+and polars manipulations). It seems that these were not installed properly.
+Please refer to Chapter~\ref{chap:user:install} for the correct install
+procedure.
+
+If \rotare was cloned using \git, you can simply call the following to download
+the libraries as well:
+\begin{lstlisting}[language=bash]
+git submodule update --init
+\end{lstlisting}
+
+If \rotare was installed manually, you either did not download the libraries or
+did not place them in the correct spot. Normally, you should have the following
+path in the directory:
+\directory{rotare/src/libs/matlab\_airfoil\_toolbox/+af\_tools/}.
